摘要

于2018年8月采用GC-MS挥发性有机物(VOCs)在线监测系统在徐州经济开发区工业区开展VOCs连续监测,并分析VOCs体积分数的时间变化特征、光化学活性差异及VOCs来源分析。结果表明,徐州经济开发区工业区总VOCs体积分数为21.6×10~(-9),从高到低依次为烷烃>芳香烃>含氧VOC>烯炔烃;芳香烃对臭氧生成潜势(OFP)的贡献率最大,烯炔烃次之,烷烃最低;运用PMF模型解析出VOCs主要来源于柴油车尾气、溶剂使用、工业排放以及汽油车尾气。其贡献分别为30%、27%、27%、16%。
        In this paper, GC-MS online monitoring system for volatile organic compounds(VOCs) was applied to carry out VOCs continuous monitoring in the industrial zone of Xuzhou economic development zone in August 2018. The time variation characteristics, photochemical activity differences and sources of VOCs volume fraction were analyzed. The results showed that the total VOCs volume fraction in the industrial zone of Xuzhou economic development zone is 21.6×10~(-9), and the order of volume fraction was: alkane > aromatic hydrocarbon>oxygen-containing volatile organic compound > enyne. Among them, aromatics contribute the most to the ozone formation potential(OFP), alkynes the next and alkane the least. The results of PMF model analysis showed that VOCs mainly comes from diesel vehicle exhaust, solvent use, industrial emissions and gasoline vehicle exhaust, and their contribution were 30%, 27%, 27% and 16% respectively.
